This species is distinguished by its uuiform coral-red colour 

 wlien seen under a strong lens, and its more convex prothorax, 

 without an)'-, or with only a very fine trace, of the longitudinal ridges 

 of nearly all its congeners.

 but, except for the shorter and stouter rostrum, the characters 

 given above show that it is a member of the Ceratopodinse, and 

 an interesting addition to that limited subfamily.
